Abstract
Most of robots working in nuclear power station adopt tether cable for communications. To prevent the cable from being entangled on the obstacles, cable reel mechanisms have been developed with dust-proof and waterproof designs for easing the cleaning of radioactive material from the robots. Problem of the existing cable reel mechanisms is that they may malfunction under large payload. Focusing on this challenge, we propose a novel cable reel mechanism (an oscillating level winder arm) with new designed dust-proof and waterproof mechanism. In addition to this, we make a fundamental experiment to inspect the validity of the oscillating level winder arm.
